A joint distribution of two successive surf parameters is provided, and it is
represented by a bivariate lognormal distribution. Consequently the joint
distribution of two successive breaker indices is represented by a bivariate
lognormal distribution. The application of the surf parameter distribution is
exemplified by estimating the probability of two successive breakers on slopes
by using wave parameters corresponding to typical field conditions.
Keywords: bivariate lognormal distribution, surf zone, surf parameter, breaker
index, breaking waves.
